How Does Modem Work?
If you want to connect your computer to an Internet Service Provider using a phone line, the computer at your end needs amodem to modulate its digital signals so they can travel down the phone line just like the sound of your voice at the same time. When the signals have reached the other end, they have to pass through a secondmodem, which demodulates them instantly so the ISP computer can understand them easily. it sends its signals through a modulator back down the line to you. After that a demodulator at your end turns the signals back into digital form that your computer can understand the signals. A modemusually contains two different kinds of translators. They are a modulator and a demodulator.
